Currently, in order to increase the maneuverability of mobile machines, technology turns of the new kinematics. Manufacturer Liebherr (Germany) released a shovel loader L-509 with the new combined system of rotation that combines rotation due to articulate the frame with the rotation of the rear wheels. This rotation provides loader kinematics several advantages: reducing the turning radius loader, which improves maneuverability shortens the path of maneuvering in the work cycle and as a result of increased machine productivity, reduction of the rotation angles of half-frames from 40-45 to 28, which provides the best layout of structural elements in the gap between the front and rear wheels on each side of the machine, as well as machine stability in the folded position. increase in shoulder restraint forces during a rollover axis front axle, increasing the safe clearance between parts of the design of the front and back half-frames. Firm ZF (Germany) offered a different constructive solution of the kinematics of the turning wheel of the tractor. Rental of construction equipment along with experienced, highly qualified machinists is available in “Golden Age”. Front steering axle APL-2000 is made with a special central beam (“pins”) in which one end is secured to the bridge at the location of the main gear, and others, ending part of the ball, connected to the tractor frame, forming a universal joint. When you turn the wheels of the main girder of the bridge shifted to the rotation by 5, making it possible to increase the angle of rotation of the wheels with respect to the machine frame at a fixed angle of rotation of the wheels relative to the bridge girders.

The total rotation angle of the wheels relative to the machine body 52, which reduces the turning radius of cars, as well as increased use of the gap between the inner edge of the wheel and the frame of the tractor for the placement of elements mounted work equipment. Currently, with the front axle APL-2000 with new kinematics of the front wheels are produced alloy Tractors Deutz-Fahr (Germany) and Steyr (Austria). Firm Carraro (Italy), created a bridge leading to the Integral castors. The angle of rotation of wheels relative to the bridge girder 62. According to the company, torque transmitted to the wheels of the tractor, even when the angle of rotation wheels of 62 remains constant. In addition, the rotation mechanism, located inside the girder bridge, is not subject to external influences when moving the machine over rough terrain.
